Most effective way to initiate sexual behavior without actually saying "do you want to engage in sexual behavior" Works well with drunk girls, Everybody knows that no one ever wants to just "come over to watch a movie"

(sexual tention is at an all time high)
Erika: Sew, what dew yew wanht tew dew?
Matt: do you want to watch a movie?
Erika: wat movie?!?!!!1
Matt: Just get on the couch.

The way guys convince girls to come over to get fucked. It makes it sound as if the guy wants to hang out instead of have sex. If you do watch a movie, you usually end up not finishing the whole thing.

Kris-Do you want to watch a movie? My place is good.
Sarah-Sure! What movie?
Kris- It doesn't matter, it's not like we'll finish it anyway.
Sarah-Wait, why?
Kris-You'll see.
